We present a Fisher matrix analysis of the combined sensitivity of upcoming CMB satellite missions and large redshift surveys to cosmological parameters. The most striking result is the enormous improvement in the potential error bars on the Hubble constant and matter density over the case of CMB data alone. This occurs because CMB anisotropies provide the sound horizon at recombination as a standard ruler. For reasonable baryon fractions, this scale may be detected as oscillations in the galaxy power spectrum, potentially yielding a 5% measure of the Hubble constant.
